[Becky Stern] likes to harness the power of the Sun. Most of us will immediately think of solar cells and other exotic solar energy techniques. But [Becky] shows how to make a hot air balloon ...

Swiss aviation pioneer Bertrand Piccard is developing a plane powered by liquid hydrogen after a much-hyped flight in 2015 ...

While some of the balloons will livestream 360-degree video and photos, others will collect data on what happens to Earth's atmosphere during a total solar eclipse. NASA's Nationwide Eclipse ...

It consists of a customized balloon, 19%-efficient thin-film cadmium telluride solar cells, an exhaust valve, control and storage modules, fixed ropes, and a cord reel, as well as an upper ...

Concentrated sunshine. With an eye to producing exquisitely clean hydrogen. researchers have demonstrated a pilot plant on the kilowatt-scale using solar hydrolysis technology, as per a paper ...

The scientists did not formally study the solar-to-hydrogen conversion efficiency in their demonstration, but they acknowledge that it is modest for this prototype. “Based on the materials ...

Iowa State students are experiencing today's solar eclipse in an out-of-this ... Today, they'll release a hydrogen-filled balloon carrying cameras, a GPS and sensors that will track temperature ...

Their ambitious goal is to be the first to circumnavigate the globe using this hydrogen-powered aircraft ... flights around the world in a balloon and a solar-powered plane called Solar Impulse.

De Rozier's experimental system consists of a hydrogen balloon and a hot air balloon tied together. Tragically, the craft explodes half an hour after takeoff. This double balloon helium/hot air ...

A balloon filled with hydrogen gas also releases heat when lit on fire. Due to differences in energy density, the crystallization of sodium acetate releases more heat per mole than the hydrogen gas ...

A balloon filled with helium and one filled with hydrogen are ignited. Hydrogen provides a loud explosion and flame. He(g) + O 2 (g) → N.R. Light the candle on the end of the yardstick and lower the ...
